INTRODUCING MEKFAB, FROM TRISTAR INTERSTELLAR At TriStar we don't build one set of tools for our clients and another for ourselves. Our cargo rides the same DropShips and JumpShips that carry yours. Our Greene-Harvester combines feed our families the way they feed yours. And when our families need defending, we arm our Guards from the same catalog we sell to you. MekFab is built in that spirit. For TriStar personnel it is a sales tool: the full capacities of every machine in the catalog, a route console for scheduling delivery, and a table of organization builder that tells a customer how much lift a force will need before anyone asks. For clients, it's the same terminal. Browse the catalog, plan the route, read the transit time and the tariff, and never have to ask us the question. Choosing a new flavor of Nitro Boost is easy. You pick one up at any corner store. We understand that a 60-ton Thunderbolt II is a harder decision. So, every design in this app comes with its full simulation file, in the format your own suites already read, and you are welcome to run our whole military catalog through your own scenarios without a word from us. Build your own tables of organization and equipment and see the lift they need. Chart a route across the Inner Sphere and see what it costs and how long it takes. Take a design to the table on a Field Sheet, or print the record sheet. You may not need us today - great! Download the app. Use it for whatever purposes you have, and know that TriStar will be here when you do. — Memphis Motor Works, a TriStar Interstellar company WHAT IT DOES • Opens MegaMek unit files (MTF and BLK) and saves back to them. • Designs 'Meks, biped and quad; combat vehicles; aerospace fighters. • Battle Value and C-bill cost computed the way MegaMek computes them. • An Engineering Review against the construction rules, in plain words. • Technical readouts, printable record sheets, and a touch Field Sheet for play. • Tables of organization from a lance to a regiment, with a DropShip lift sheet. • NAV-OPS: 3,174 systems, 30 light-year jump routes, transit days and recharges. • No account.

Verdict
The clearest difference is in-app purchases: MekFab at none against Radio Messenger's 2. MekFab also leads on update cadence (every 2 days vs every 3 weeks). Radio Messenger's advantage is ratings volume (13 vs 1). On price, rating, ads and device support there is nothing between them.
